Maybe in the fanfiction, Ezra has some unique skills or knowledge that the Mandalorian's harem finds useful. For example, he could have some understanding of ancient Jedi artifacts that are relevant to a mission they are all on. This could lead to interesting interactions and the development of relationships within the harem.
One popular theme is Ezra's growth and development. Fans often write about how he becomes a more powerful Jedi. Another theme is his relationships, like his friendship with the other rebels or a possible romantic relationship. Time - travel is also a theme that pops up sometimes, where Ezra goes back in time to change certain events in the Star Wars universe.
The theme of Ezra's place in the larger Star Wars narrative is also quite common. Fanfics may explore how he fits into the events that are happening across the galaxy, his role in the fight against the Empire, and how his actions impact the overall story. Some might even imagine alternative storylines where Ezra's decisions lead to different outcomes for the galaxy.
There could be a fanfiction where Ezra as a girl has a more prominent role in the Force. It could show how she might use the Force in ways that are unique to her female perspective. For instance, she might be more in tune with the nurturing aspects of the Force, using it to heal or connect with nature in the Star Wars setting. This would be different from the traditional male - dominated Force - using characters we often see.
One common theme is the struggle to overcome physical and emotional pain. Ezra might be injured in a battle and then have to deal with the trauma, both in terms of his own self - doubt and how it affects his relationships with other characters.
One common theme is his discovery of the Force. Writers often explore how a young Ezra first starts to sense and interact with the Force, which can be really exciting to read. For example, he might have small, mysterious experiences like making objects move slightly without realizing it at first.
In the fanfiction, Ezra getting the Mandalorian armor might change his role in the story significantly. He could become more of a stealthy and formidable fighter. The armor might also come with its own set of challenges, like learning to use its various functions and dealing with the cultural significance of wearing Mandalorian armor as an outsider.
